Nano formulations and inducer chemicals having antimicrobial property against Alternaria leaf blight of potato

Title:Nano Formulations and Inducer Chemicals having Antimicrobial Property against Alternaria Leaf Blight of potato

Abstract

Potato (Solanum tuberosum) is one of mankind’s most valuable food crops in the world.Potato crops are affected by a large number of foliar diseases. Among them, Alternaria leafspot of potato (Alternaria solani) most important diseases causing heavy yield losses.Hence, in the present investigation, an efficient and potential modern approach throughresearch studies was carried out related to management of agriculturally importantpathogens of potato crop. Under In vitro study, Seven chemicals namely Silver-Nanoparticle (AgNPs), AgNO3, Silvox (H202+AgN03), Chitosan, Salicylic acid, H2O2 andIsoprothiolane (Check Chemical) were evaluated in different concentrations against fungalpathogen Alternaria solani under in-vitro and in-vivo condition. Out of seven chemicals sofar tested under in-vitro study, AgNO3 @ 10.7 ppm appeared to be most effective in  respect of mycelia growth inhibition against Alternaria solani. The H2O2 and Salicylic acid exhibited maximum disease suppression due to prophylactic use at 50 ppm concentration (H2O2-72.74 % and Salicylic acid -78.96%) as compared to check chemical Isoprothiolane (54.54% at 50 ppm).

Antimicrobial efficacy of Nano-formulation and Inducer chemical against Phomopsis Blight of Brinjal

Antimicrobial efficacy of Nano-formulation and Inducer chemical against Phomopsis Blight of Brinjal

Abstract

Phomopsis vexans is one of the most important pathogen of brinjal which cause leaf blight and fruit rot of brinjal that lead to heavy yield loss in field condition. Hence, in present study, an efficient research studies carried out related to management of agricultural important pathogen of brinjal crop. Under in-vitro study seven chemical namely silver Nanoparticle (AgNPs), AgNO3, Silvox(H2O2+ AgNO3), Chitosan, Salicylic acid, H2O2, Isoprotiolane(check chemical) were evaluated in different concentration against fungal pathogen Phomopsis vexans, under in-vitro and in-vivo condition. In in-vitro condition out of seven chemical AgNO3@ 4.89 ppm appeared to be most effective in respect of mycellial growth inhibition against Phomopsis vexans. The H2O2 and Salicylic acid exhibited maximum disease suppression due to prophylatic use at 50ppm concentration (H2O2-64.72% & Salicylic acid-68.45%) as compared to check chemical Isoprothiolane.

Evaluation of antimicrobial property of nano-formulation and inducer chemical against Colletotrichum capsici on chilli

Evaluation of antimicrobial property of nano-formulation and inducer chemical against Colletotrichum capsici on chilli

Abstract

Chilli (Capsicum annuum) is one of the most important solanaceaus crop in India. Chilli crop affected by a large no of foliar disease. Among them, chilli anthracnose caused leaf blight and fruit rot is one of the most important diseases causing heavy yield loss. Hence, an efficient research studies carried out related to management of agricultural important pathogen of chilli crop. Under in-vitro study seven chemical namely silver Nanoparticle (AgNPs), AgNO3, Silvox (H2O2 + AgNO3), Chitosan, Salicylic acid, H2O2, Isoprotiolane (check chemical) were evaluated in different concentration against fungal pathogen Colletotrichum capsici, under in-vitro and in-vivo condition. In in-vitro condition out of seven chemical H2O2@ 9.66 ppm appeared to be most effective which was followed by Silvox (12.07 ppm) in respect of mycellial growth inhibition against Colletotrichum capsici as compared to check chemical Isoprothiolane. In-vivo condition it recorded that curative application of nano-formulation resulted significant disease suppression at 50ppm (Silver Nanoparticle-(AgNPs)-80.96%, AgNO3-60.0%, Silvox-84.01% and Chitosan-61.93%) as compared to check chemical Isoprothiolane (57.93%)at 50ppm.
